Solutions

1. Verify the username exists in sys_user before calling userQuit.
2. Ensure the username comes from the authenticated principal rather than free-form input.
3. Check for case sensitivity and trailing whitespace in the username.
4. Confirm the user was not deleted by a concurrent admin action.

Example fix

// before
userService.userQuit(username); // null user -> throws

// after
SysUser u = userMapper.getUserByName(username);
if (u == null) return Result.error("用户不存在");
userService.userQuit(username);

SysUser u = userMapper.getUserByName(username);
if (u == null) return Result.error("用户不存在");
userService.userQuit(username);

boolean userExistsByName(String username) {
  return userMapper.getUserByName(username) != null;
}

try { userService.userQuit(username); }
catch (JeecgBootException e) {
  if (e.getMessage().contains("已不存在")) return Result.error("用户不存在或已删除");
  throw e;
}

When it happens

Trigger: Calling userQuit with a username that does not exist in sys_user (getUserByName returns null).

Common situations: Username typo; the user was already hard-deleted; username case mismatch; the logged-in principal's username no longer matches a DB row after a rename; tenant context filters the user out.
